WASHINGTON – There's one certainty for the Capitol's most liberal lawmakers now that Democrats will control Congress: They won't have to meet in the basement anymore.

“One time they put us in the most obscure, smallest meeting room in the farthest corner,” Oregon Rep. Peter DeFazio said of life for progressive Democrats under Republican control. Now, “we should be able to score a regular and accessible meeting place.”

That may be the easy part.

Accustomed to pleading in obscurity for causes such as universal health care, come January these progressives from Northern California, Massachusetts and elsewhere will be part of the congressional majority and in a position to actually do something about them.

Yet they risk getting pinched between liberals itching for impeachment hearings and a quick end to the Iraq war, and more centrist Democrats looking to find common cause with the GOP on fiscal issues.

And that's assuming progressives can settle on their own goals from a long list of priorities, including universal health care, action on the aftermath of Hurricane Katrina, voting reform and fixing the trade imbalance.

“Most of us had one drink on election night and then got really sober,” said Rep. Jim McDermott, D-Wash. “We're sort of in the dog-who-caught-the-bus situation. Now that we have it, what do we do with it?”

The Progressive Caucus, founded in 1991 over frustration with the policies of the first Bush administration, claimed 63 members this year and says it is the largest active Democratic caucus in the House. The moderate New Democrats and “Blue Dog” Democrats each have more than 40 members, with significant overlap.

The 41 new Democratic House members elected in November include a number of moderates in Republican-leaning districts. The Blue Dogs already claim nine new recruits while the Progressive Caucus only names two to date (though it says more are expected), signaling potential difficulties ahead for progressives facing off against newly empowered moderates.

“The vast majority, maybe two-thirds of the Democratic Caucus, or over two-thirds, are not members of the Progressive Caucus, and that says volumes,” said California Rep. Dennis Cardoza, D-Atwater, a Blue Dog member.

But expectations from left-wing constituencies are high after 12 years that saw scant discussion of liberal priorities such as health care reform, education investment, affordable housing and trade protections. Troop withdrawal from Iraq is perhaps the top issue, though progressives don't have a unified position on how fast it should happen.

“We'll need progressives to use their committee chairmanships to help put big ideas back on the agenda,” said Robert Borosage, co-director of the Campaign for America's Future, which participates in a bimonthly strategy session that includes aides to progressive House members.

Liberals will have little tolerance for Democrats who prefer to play ball with President Bush and the Republicans, Borosage said.

“This is not a time when people are going to have much patience for that kind of collaboration,” he said.
